compatible burner?

Ive been having some issues with burning dvds through Encore. When I try to run discs Ive burnt on a dvd player or through my duplicator I get some of the following problems; Pixelation, the disc stops, inability to duplicate, etc. I cant single out why this problem exists and it seems to happen rather randomly. Some work some dont! I am just wondering if the dics burners Im using are right. Im currently burning with an external PIONEER DVD-RW DVD-106D USB DEVICE and an internal LITE-ON DVDRW SOHW-8125. I cant find either of these on Adobes compatible DVD burners on their website. If these dont work which would be the best?
